When a widow leaves "her right" to a piece of property, what exactly does that mean? Has she acquired the property from her husband when he died, did she acquire it as an heir of her own family, or ...?

In this will of Elizabeth Skillicorn als Ceiggeen of Lonan, 1721/22, "She Left to her Son Henry Skillicorn her Right of the Estate of the Ballaraugh if he would Accept of the Same; otherwise to her Son and Grand Son John and Jon Skillicorn"

Your help much appreciated.
